Description

Clutch mechanism and film coating transfer device of film coating transfer device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clutch mechanism of a film coating transfer apparatus and a film coating transfer apparatus provided with the clutch mechanism, and more particularly, to transfer a coating film such as a quartz coating layer or an adhesive layer on a film coating transfer tape to the ground or the like. In addition, in the film coating transfer device having a configuration for automatically recovering the coated film transfer tape after use, the clutch for synchronizing the unloading speed and the winding speed of the film coating tape in the unloading reel and the reel winding It's about technology.

An example of the structure of this kind of film-coated transfer apparatus is shown in FIG. 20, and the transfer apparatus is a carrying-out reel wound by mounting a film-coated transfer tape b in a case a which can be operated by one hand. c) and the winding reel (d) for recovering the used film-coated transfer tape (b ') are rotatably installed, and the film-coated transfer tape (b) is transferred to the tip of the case (a). The film coating transfer head f pressurized on the protrusion is provided. In addition, the reels (c) and (d) described above are self-winding type connected to each other by the interlocking device g. The linkage device g is formed by alternately meshing gears h and i provided in the outer peripheral portions of the reels c and d described above. And when this film coating transfer apparatus is used as an erasing tool for correcting a typo, etc., the said case (a) is grasped with one hand, and the film coating transfer is carried out by the press part j of the said head f. The case a is moved in a predetermined direction while pressing the tape b in close contact with the to-be-modified portion (transferred portion). Thereby, the correction coating layer of the film coating transfer tape b in the press part j of the said head f is coated on said to-be-modified part, erases a character, etc., and at the same time uses the film coating after use The transfer tape b 'is automatically wound on the reel d wound and recovered.

In this case, the outer diameter of the film-coated transfer tape (b) in the carrying out reel (c) decreases with use, while the outer diameter of the film-coated transfer tape (b ') in the reel (d) is increased. do. On the other hand, the rotation ratio (corresponding to the gear ratio of the linkage device g described above) between the carrying-out reel c and the winding reel d is always constant. For this reason, the winding speed of the winding reel d tends to be faster as time passes compared to the carrying speed of the carrying reel. In order to prevent this, it is necessary to synchronize the take-out speed and the winding speed. For this purpose, the above-mentioned carrying out reel c is provided with the clutch mechanism k which synchronizes the above-mentioned carrying out speed and the winding speed.

That is, the said carrying out reel (c) is rotatably supported by the projection part (m) of the drive gear (h) by the support shaft (n), and winds the film-coated transfer tape (b) around the projection part (m). The tape carrying core (o) attached to the stand is rotatably fitted, and the clutch mechanism (k) described above is provided between the protrusion (m) and the tape carrying core (o).

The clutch mechanism k has a plurality of engaging portions provided with a clutch pawl p, which is elastically deformable in the radial direction provided on the outer circumference of the protrusion m, provided on the inner circumference of the tape carrying core o. It is elastically detachably engaged with (q).

Then, the winding speed is increased with time as compared with the above-mentioned discharging speed, and the synchronization of these two speeds collapses, so that the rotational torque acting on the tape discharging core o becomes large. As a result of k), as a result of the tape carrying core o slidingly rotating with respect to the above-mentioned protrusion part m, the said carrying out speed is synchronized with said winding speed.

However, in such a clutch mechanism k, the engagement and disengagement operations of the clutch pawls p and q and the engaging portion q are elastically 'clicked' and intermittently intermittently. Since it is repeated, the user's hand is uncomfortable and the running of the film-coated transfer tape b is not constant. Furthermore, the above-described engagement and disengaging operations are continued to be used for carrying out and winding speed. As there is a problem that as the difference between the two increases, there is a problem that the above-mentioned discomfort and running irregularity become remarkable, further improvement is desired.

In this regard, the present inventor has already proposed the clutch mechanism r as shown in Fig. 21 (see, for example, Japanese Patent Laid-Open No. 5-58097). The clutch mechanism r is inserted between the cylindrical outer circumference of the protrusion m and the cylindrical inner circumference of the tape carrying core o in a state in which friction members s, such as elastic O-rings, are engaged with friction. Is made.

According to the clutch mechanism r, the three elements m, s, and o are relatively smoothly slid in the synchronous operation described above. The discomfort and driving irregularities caused by constant and intermittent repetitive motions have been eliminated.

However, in the structure of this clutch mechanism r, the frictional member s is obtained by the operation transfer using the frictional force by the radial load between the above-mentioned three elements m, s, and o. The design and manufacturing conditions of the steel were very demanding, which made it difficult to manufacture, which impeded the reduction of manufacturing cost.

That is, when said frictional force is too strong, there exists a tendency for operation feeling to become heavy too much in an operation | movement late. On the other hand, when the frictional force is too weak, the operation feeling tends to be too light in the initial stage of use. Therefore, the frictional force should be set to an optimum value in consideration of these relationships.

Therefore, in order to obtain the optimum value of the frictional force, in designing and manufacturing the friction member s, the inner diameter and the outer diameter thereof are adapted to the cylindrical inner diameter of the protrusion m and the cylindrical inner diameter of the tape carrying core o, respectively. Although the friction member s itself also has elasticity, it is necessary to consider the thickness dimension in the radial direction. Therefore, after assembling the clutch mechanism r, processing for finely adjusting the shape dimension of the friction member s may sometimes be required.

In addition, since the diameter dimensions and the like of the friction member s are set to be difficult, the assembly of the friction member s between the cylindrical outer circumference of the projection m and the cylindrical inner circumference of the tape carrying core o is also performed. It is difficult to assemble, for example, it is necessary to forcibly add.

An object of the present invention is to provide a novel clutch mechanism that solves such a conventional problem.

The configuration of the clutch mechanism of the present invention is such that, in a case which can be operated by one hand, the reel having the film coated transfer tape wound and mounted thereon and the winding reel for collecting the film coated transfer tape after use are rotatably installed. In the self-winding film-coated transfer apparatus having a winding reel interlocked with the above-mentioned reel, the reel is mounted on at least one of the above-mentioned reels, and the take-out speed and the winding speed of the film-coated transfer tape on both reels are adjusted. By synchronizing, the tape core which winds and rotates the film-coated transfer tape is supported in a state of being fitted by a rotation driving unit for rotationally driving the tape core and an engaging support member engaged in the axial direction with the rotation driving unit, The tape core and the rotary drive unit are rotated by a power transmission means utilizing friction force by thrust load. Frictionally engaged, the power transmission means comprises a plurality of frictionally engaging members that are elastically deformable in the axial direction, which are integrally provided on at least one of the above-mentioned rotational driving portion and the engaging support member, The alignment member is elastically engaged under a predetermined pressure on the axial end face of the tape core by the axial engagement force between the rotation driving unit and the engagement support member.

The film coating transfer head which presses the said film coating transfer tape on a to-be-transferred part is provided, and the said clutch mechanism is provided in at least one of the said both reels.

The film-coated transfer apparatus provided with the clutch mechanism has a configuration in which it is discarded after use discarded by the consumption of the film-coated transfer tape, and has a refillable configuration in which the film-coated transfer tape can be replaced as a consumable. There is.

In the film-coated transfer apparatus of the present invention, the winding speed of the reel is increased with time as compared with the discharging speed of the unloading reel, and as a result, their motives are broken, and as a result, the tape-coated transfer tape is wound around the tape core to be rotated. The actuating torque becomes large, but the clutch mechanism causes the tape core to rotate relative to the rotational drive, thereby eliminating the difference in rotation torque between the two, so that the ejection speed is synchronized with the winding speed.

In this case, the tape core and the rotational drive portion are frictionally engaged in the rotational direction by a power transmission means utilizing frictional force due to the thrust load, so that the tape core and the rotational drive portion are relatively smooth during the above synchronous operation. It will slide.

The frictional engagement force of the power transmission means is set to an optimal value by appropriately adjusting the engagement dimension relationship between the rotational drive portion and the engagement support member in the axial direction, and setting the axial engagement force between them.

In this holding position, the pressing portion 4a of the head 4 is placed on the start end (left end) of the to-be-modified portion (transferred portion) 40 on the corrected ground such as a typographical error. ) Is moved horizontally, i.e., in the right direction with respect to the ground, and stopped at the end (right end) of the part to be modified 40.

By the above operation, the correction coating layer (white) 41 of the film-coated transfer tape T in the pressing portion 4a of the head 4 is peeled from the film base material described above. It is transferred and coated on the crystal part 40. As a result, misspellings and the like can be erased and the correct character can be written directly thereon.

In addition, when looking into the mechanism operation inside the film coating transfer apparatus 1, the tensile force applied to the film coating transfer tape T by the pressure operation of the film coating transfer head 4 as described above (Fig. 1B). When the arrow A direction) acts as a rotational torque on the unloading reel 2, the unloading rotary gear 12 rotates through the tape core 10 of the unloading reel 2 and the clutch mechanism 6 again. This rotational force is rotated by the interlocking device 5 by interlocking the winding reel 3 and the winding reel 3 integrally therewith, thereby automatically winding the film-coated transfer tape T 'after use.

In this case, the film-coated transfer tape T in the take-out reel 2 has a constant rotation ratio (corresponding to the gear ratio of the interlocking device 5) between the take-out rotary gear 12 and the winding rotary gear 13 at all times. The ratio between the outer diameter and the outer diameter of the film-coated transfer tape T 'in the winding reel 3 changes over time and is not constant. That is, the outer diameter of the film-coated transfer tape T in the carrying out reel 2 gradually decreases with use, whereas the outer diameter of the film-coated transfer tape T 'in the reel 3 becomes larger. You lose.

Therefore, the winding speed of the winding reel 3 becomes faster as time passes compared to the carrying speed of the carrying out reel 2, and the synchronization of these two speeds is broken, and the rotational torque acting on the carrying out reel 2 is also increased. It grows bigger. Then, the rotational torque overwhelms the frictional force of the clutch mechanism 6, and the tape core 10 slides with respect to the take-out rotary gear 12, resulting in rotation between the above-described reels 2, 3 The torque difference is eliminated, and the above-mentioned discharging speed is synchronized with the winding speed, so that smooth running of the film-coated transfer tape T is ensured.

As described above, the power transmission in the clutch mechanism 6 utilizes the frictional force due to the thrust load between the tape core 10 and the engaging projection 30 of the ejection rotary gear 12. In the configuration of the clutch mechanism 6, the frictional force can be set to an optimum value by appropriately adjusting the relational dimension in the thrust direction between the structural members 2, 12, and 31.

In addition, when the film-coated transfer tape T between the take-out reel 2 and the reel 3 is loose due to an operator's mistake, etc., the rewind button 31 is moved outside the case 7. The rotation operation (rotation in the direction of arrow B in Fig. 1) in the rewinding direction eliminates the loosening of the film-coated transfer tape T.

In this case, the rotational force in the rewinding direction B applied to the rewind button 31 is directly transmitted to the tape core 10 through the axial engagement portion and the rotary engagement portion 35 for both purposes. It rotates in the direction B which rewinds (10). The tape core of the rotary gears 12 and 13 of the linkage device 5 and the reel 3 wound by the reverse rotation preventing force by the reverse rotation prevention mechanism 25 and the sliding action of the clutch mechanism 6 11) is at rest. As a result, loosening of the film-coated transfer tape T between the reels 2 and 3 described above is eliminated.
